Bottle cap opener

Abstract

There is provided a bottle cap opener comprising: a cylindrical body including an upper cylindrical body and a lower cylindrical body; an elongate screw bar passing through the upper cylindrical body at a center thereof, and passing beyond the upper cylindrical body upwards; a handle coupled to the elongate screw bar at a top end thereof; a screw protrusion coupled to the elongate screw bar at a bottom end thereof; both wings pivotally coupled to the upper cylindrical body at both-side pivotal portions thereof via both-side pivotal shafts respectively; and a silicon-based cap gripper formed on an inner face of the lower cylindrical body so as to grip a bottle cap tightly therein.

What is claimed is: 
     
       1. A bottle cap opener comprising:
 a cylindrical body including an upper cylindrical body and a lower cylindrical body; 
 an elongate screw bar passing through the upper cylindrical body at a center thereof, and passing beyond the upper cylindrical body upwards; 
 a handle coupled to the elongate screw bar at a top end thereof; 
 a screw protrusion coupled to the elongate screw bar at a bottom end thereof, the screw protrusion being configured to be fixed to a bottle cap by rotating the handle; 
 left and right wings pivotally coupled to the upper cylindrical body at left and right pivotal portions thereof via left and right pivotal shafts, respectively; and 
 a silicon-based cap gripper formed on an inner face of the lower cylindrical body, wherein the left and right wings are configured such that a pivotal movement of the left and right wings enables the silicon-based cap gripper to grip the bottle cap tightly therein, thereby allowing a user to open the bottle cap easily by rotating the handle. 
 
     
     
       2. The bottle cap opener of  claim 1 , wherein the lower cylindrical body is vertically divided into two lower half cylindrical bodies, wherein each of two lower half cylindrical bodies has vertical edges with engaging convex and concave portions. 
     
     
       3. The bottle cap opener of  claim 1 , wherein the upper cylindrical body has a handle orientation-change groove defined therein, wherein an orientation of the handle changes from a vertical orientation to a horizontal orientation via the handle orientation-change groove. 
     
     
       4. The bottle cap opener of  claim 3 , wherein, when the handle has the horizontal orientation, the handle is replaced with a L shaped rotation handle including a horizontal portion and a vertical portion coupled thereto. 
     
     
       5. The bottle cap opener of  claim 1 , wherein the silicon-based cap gripper has a threaded inner face. 
     
     
       6. The bottle cap opener of  claim 1 , wherein the screw protrusion extends in a spiral shape.
